Getting Dwarf Baby Tears to ROOT
Greetings, all -
I've been trying without success for about two years to get dwarf baby tears to root.
I have a 36 gallon bowfront tank with CO2 injection and strong lighting (a dual-tube T5 fixture plus an LED fixture, T5 has a Geismann Superflora and a Geismann tropic tube). The substrate is a mix of gravel plus ADA Aqua Amazonia soil.
My baby tears are growing really nicely BUT i can't get them to root in the substrate. I've tried a number of things: I've tied them to a few large flat rocks, small pieces of driftwood. I've tried weighting them down with plant weights (non-lead) in the hopes that they'd send out runners and attach themselves to the gravel. I've tried doing that and then sprinkling a little soil on top and hoping that they'd take the hint.
After some number of weeks or a couple months, they come loose and all end up at the top of the tank again. They look lovely up there, they grow well in the light. To be sure, they appear to be doing just fine on the bottom, they just don't *root*.
How in the world do people get nice carpets of dwarf baby tears? What should I try next?
